Benefits of Thermal Mass Flow for the Measurement of Gases

There are quite a few technologies available to measure flowing gases. When the comparisons are complete, most outcomes point out that thermal mass flow technology is superior to others. This short video explores those benefits and demonstrates why thermal mass flow measurement technology is the right choice for your gas flow measurement application.

Benefits of Thermal Mass Flow Technology:

  • Direct mass flow measurement of air and gases in standard volumetric units (e.g., SCFM or NM3/H) or mass units (e.g., LBS/M or KG/H)
  • No additional pressure or temperature compensation required
  • Repeatability and exceptionally broad measurement range: up to 1000:1 (100:1 typical)
  • Standard linear 4-20mA output proportional to mass flow rate
  • Low pressure drop
  • No moving parts
  • Cost-effective
  • Insertion, Inline & remote* styles
  • Measures flow rate and temperature

Along with these benefits, Fox Thermal improved thermal mass flow with their DDC-Sensor (Digital Sensor Technology). Because of this unique development, Fox Thermal leads the industry for accuracy, quality, and innovative design.
